Horologium (pronounced /ˌhɒroʊˈlɒdʒiəm/ or /ˌhɔrəˈloʊdʒiəm/, Latin: clock) is one of the lesser southern constellations (declination around −60 degrees).
Originally named Horologium Oscillitorium by Abbé Nicolas Louis de Lacaille, the constellation name has since been shortened to be less cumbersome. Horologium Oscillitorium was to honour the inventor of the pendulum clock, Christian Huygens.
Since it was invented in the 17th century, and not visible in the Mediterranean there is no earlier mythology associated with it.
